Beschreibung

boolImagick::setImageOpacity
( float$opacity
)

Sets the image to the specified opacity level. Diese Funktion ist verfügbar, wenn Imagick gegen die ImageMagick-Version 6.3.1 oder höher kompiliert wurde.
This method operates on all channels, which means that for example opacity value
of 0.5 will set all transparent areas to partially opaque. To add transparency to
areas that are not already transparent use Imagick::evaluateImage()
